Shell and Coil Heat Exchangers
HEXONIC shell and coil heat exchangers consist of a shell and a coil, thanks to which they achieve a higher heat transfer coefficient compared to standard shell-and-tube heat exchangers. Their compact dimensions in relation to the heat exchange surface and the associated high efficiency are appreciated by many installers and users.
The HEXONIC shell and coil exchanger range includes compact low-power models, installation-ready kits, proven general-purpose designs, and specialist refrigerant exchangers for heat pumps. This gives users a flexible portfolio covering small CH and DHW duties, HVAC and industrial applications, food and chemical processes, and ground source heat pump systems.

H
The HEXONIC H shell and coil heat exchanger is an economic solution for small CH and DHW systems. It extends the shell and tube exchanger range with the smallest exchangers built on a tube coil design, combining high performance with compact size relative to heat exchange surface.
The H series was developed to meet the requirements of the smallest industrial systems and heating substations...
...especially where plate exchangers cannot be used for various reasons such as high contamination or aggressive environments. Versions with threaded and flanged connections are available to maximise adaptation to local conditions and facilitate installation.
Key benefits of the H series include compact size, high efficiency, cost-effective operation, and suitability for environments where plate exchangers are not practical. Corrugated tubes intensify heat transfer, and the possibility of vertical installation reduces required installation space.
Typical H applications include small CH systems, small DHW systems, industrial systems, heating substations, HVAC, steam systems, food industry, chemical industry, cooling, renewable energy, heat pumps, geothermal systems, solar collectors, oil cooling, refrigeration, and sewage treatment.
HAD
The HEXONIC HAD shell and coil heat exchanger is a fully equipped, installation-ready kit consisting of an exchanger, mount, and insulation. Developed as an advanced version of the shell and coil exchanger, HAD combines the core benefits of this exchanger type with new design solutions that simplify installation and improve overall economy.
As a result of advanced design work, the HAD features horizontal-position connections...
...factory-supplied insulation, and a pre-installed mount. These features facilitate mounting in horizontal installations and help shorten and simplify the entire installation process. At the same time, HAD remains a cost-efficient solution for a wide range of temperature, pressure, flow speed, and operating media requirements.
Key benefits of the HAD include easy installation, compact size, high efficiency, low operating costs, and flexibility across many applications. It is suitable for HVAC, heating, district heating substations, renewable energy, solar collector systems, heat pumps, geothermal installations, cooling, steam systems, food industry, chemical industry, oil cooling, power industry, refrigeration, and sewage treatment.
JAD
JAD shell and coil heat exchangers are presented by HEXONIC as the solution for the most demanding applications. Within the overall shell and coil portfolio, JAD represents the established general-purpose and higher-duty product family for users who need dependable performance across a wide operating range.
As the core shell and coil platform in this category, JAD is positioned...
...for demanding thermal duties where compact dimensions, high efficiency, and durable design are critical. It serves as the reference family from which smaller specialized variants such as H and S are derived. This makes JAD the broad-application backbone of the HEXONIC shell and coil offer. Based on the category-page wording, it is best positioned as the standard high-capability shell and coil solution for installers and engineers needing robust performance.
S
The HEXONIC S shell and coil heat exchanger is a compact solution designed for low power systems. Its small dimensions and compact connection layout make it especially suitable wherever limited installation space or low system power prevent the use of larger exchangers.
The S type exchangers are special versions of the smallest JAD exchanger models.
In addition to their more compact size, they allow reduced pressure losses on the shell side while maintaining high flow speed. They are available in a regular version with perpendicular connections and in an X-shaped version that combines the advantages of JAD X exchangers with the compact S-series form factor.
Key benefits of the S series include space-saving installation, low shell-side pressure losses, high efficiency, compact layout, and flexible connection options. Typical applications include HVAC, steam systems, food industry, brewing, beverage manufacturing, oil manufacturing, CIP stations, chemical industry, cooling, heating, district heating substations, renewable energy, geothermal systems, heat pumps, solar collector systems, oil cooling, power industry, and refrigeration.
RAD
The HEXONIC RAD shell and coil heat exchanger is dedicated to ground source heat pumps and other refrigerant applications where proven design, strong thermal performance, and compact installation are essential. It is especially suited to systems powered by water from a well, lake, or river.
Direct refrigerant inlet into each of the heat exchanger tubes ensures...
....uniform medium distribution and low maldistribution risk. The RAD offers a high heat transfer coefficient, is designed for modern refrigerants including A2L options such as R32, R452B, and R454B, and is also optimised for propane R290. With compact dimensions and the possibility of vertical installation, the exchanger footprint is greatly reduced. The RAD is designed to work with pressures up to 45 bar.
Key benefits of the RAD include compatibility with modern refrigerants, uniform refrigerant distribution, compact size, corrosion resistance, easy assembly, and suitability for refrigerant-side ground source heat pump duty. It is specifically targeted at heat pump systems using well, lake, or river water sources.
Frequently Asked Questions
HEXONIC presents shell and coil heat exchangers as a solution offering higher heat transfer coefficient than standard shell-and-tube exchangers, together with compact dimensions and high efficiency. Within the range, different models are used for small CH and DHW systems, HVAC, heating, food and chemical processes, refrigeration, and specialist ground source heat pump refrigerant applications.
H is the economical small-system option for CH and DHW duties. HAD is the installation-ready version supplied with mount and insulation. JAD is the core shell and coil solution for demanding applications. S is the compact low-power version derived from the smallest JAD models. RAD is the specialist refrigerant exchanger dedicated to ground source heat pumps.
RAD is the most suitable model for ground source heat pump refrigerant applications because it is specifically dedicated to that duty and is designed for modern refrigerants including A2L options and propane R290.
H and S are the most compact options in the shell and coil range. H is best for small CH and DHW systems, while S is intended for low-power systems where very compact installation and reduced shell-side pressure drop are important.
